7:08utc H1 Back To OBSERVING

During shift Hand-off of an H1 in NOMINAL LOW NOISE, I accepted SDF diffs which came up.  We were at a nice range of 118Mpc. 

SDF Diffs

The Diffs are attached and were:

1) SUSIM for IM1, IM2, & IM3

These are known and related to a change Cheryl made for relocking.  She will make an alog about this.

2) ASC:  RPC gains

Have a few small gain changes for ASC-RPC_DHARD & CHARD pit/yaw.  These looked new to me (what's "RPC"?) & Cheryl was not familiar with them as well.  I did a quick scan of ASC medms, but I could not track them down.  Nevertheless, I went ahead and accepted them.

 

Note for OBSERVATORY MODE:  The last 2.5-3hrs of downtime was listed as OBSERVING (vs. LOCK ACQUISITION or EARTHQUAKE).  I switched it very briefly to LOCK ACQUISITION so we can mark that we were in fact down due to a lockloss.
